Protests supporting Gaza take place in Europe

Israeli bombardment and shelling continued in Gaza City on Saturday morning, though at a lower intensity than before Hamas expressed its willingness to release all hostages as part of President Donald Trump's proposed ceasefire plan.

Meanwhile, the Israel Defense Forces' Arabic language spokesperson Lt. Col. Avichay Adraee issued a warning to Gaza residents, saying the area north of Wadi Gaza -- the centrally-located river valley that divides the northern and southern ends of the strip -- "is still considered a dangerous combat zone."

"IDF forces continue to surround Gaza City, and attempts to return there pose a significant risk," Avichay wrote in a post on X. "For your safety, avoid returning north or approaching IDF operations areas anywhere in the strip -- even in the south.

Israel's Prime Minister Benjamin Netanyahu has instructed the Israel Defense Forces to halt all offensive operations in the Gaza Strip, with only defensive measures now permitted, two Israeli sources familiar with the matter told ABC News on Saturday morning.

Both sources stressed that Israel will work "in full coordination" with U.S. President Donald Trump and his administration to end the Gaza war based on the principles set forth in his proposed 20-point plan.

The sources added that it is a "top priority" for Israel to get all the hostages out of Gaza as soon as possible.

Both sources also said that Israel is preparing to send a negotiating team, which will likely depart in the next couple days.

One of the sources told ABC News that negotiations may take place in the Egyptian capital Cairo rather than the Qatari capital Doha.

Palestinian Islamic Jihad and the Popular Resistance Committees issued statements on Saturday expressing their support for Hamas' response to the proposed Gaza ceasefire deal, after Hamas said it was ready to release all hostages.

PIJ and the PRC -- both recognized as terrorist organizations in the U.S. -- said in separate posts to Telegram that they were consulted by Hamas on President Donald Trump's proposed ceasefire agreement.

Hamas' response -- which said the group was ready to release all hostages but that more negotiations were needed for a full agreement -- was "an expression of the position of the Palestinian resistance forces," PIJ said.

The PRC praised the "constructive and responsible stance of Hamas, on behalf of the Palestinian forces and factions."

"The time has come for this occupation to be lifted from our land," the PRC said. "Our people have the right to live a dignified life without killing, destruction, displacement and settlement."
